KLINGLER I AUXILIARY IGNITION SYSTEM 2 Sheets-Sheet 2 Filed Deo. l, 1951 Patented F eb. 27, 1934 UNITED STATES-2- PATENT oFFlcE provide an auxiliary ignition system of the type` vdescribed which is `designed to operate in conjunction with the regular or existent ignition sysl tem, for instance, in an automobile, and to be` set into action to assist and improve the operation of starting the engine, and adapted for use as an emergency ignition system when the regular or existent system is disabled. l It is also an important object of my invention to `provide an auxiliary ignition systenr of the type described which may be manually connected with the existent ignition system, which may he manually disconnected therefrom, or manually 2D arranged so as to substitute for the existent ignition system, cutting out of operation the said Vexisting ignition system.

' It is also an important object of this invention to provide means incorporated in an auinliary ignition system of the type described which operates to synchronize the action of the said auxiliary ignition system whereby the eiective power impulses generated by the said auxiliary ignition system are confined and limited to such periods 80 in the operation of the engine as will bring about the most perfect coordination, for instance, between ignition spark and piston position, thereby eliminating the defective and imperfectly syn- ,'chronized relationship of ignition spark and pis- Il ton position which very frequently obtains in a regular ignition system, particularly if any of the Figure 3 is a transverse vvertical section taken approximately on the line 3-3 of Figure 2 looking' -in the direction of the arrows. I

Figure 4 is a view similar to Figure 3 taken approximately on the line 4 4 of Figure 2 also looking in the direction of the arrows.

Figure 5 is a perspective view of-an amature of one of the coils ofthe device of the invention.

In the drawings wherein for purposes of illustration is shown a preferred embodiment of my invention, the numeral 5 designates generally the manual switch control of the device Iof the invention which may be mounted upon the instrument board or the like convenient location adjacent the position of the operator of the automobile or the like. It consists of, a casing 6 receiving slidably 1' therethrough a rod '7 provided at one end with the suitable dielectric handle 8.

. The end of the casing 6 adjacent the handle 8 isprovided with a'dielectric closure plate 9 having an inward extension '10 vertically bored to receive an outwardly spring pressed detent 11 adapted to engage with either of a pair of notches 12, 13 in the adjacent side of the bar '1. 'lhe bar 'I- is normally projected in the direction of its handle by a spring 14 thereon which loperates with and is extended between a sleeve 1 5 anchored on the bar and with a similar spring holder 16 secured to the back of the casing or not as desired. The handle is maintained in the full inward position shown in Figure 2 by the detent 1l seating in the small notch 11a-in the underside of the bar 'l outward of the large notch 13. l

Intermediate the ends of the bar 'I and rigidly connected thereto is an insulating bushing 16 carrying a spool-shaped conductive member 17 35 havingthe flanges 18 and 19, which act as contacts. From one side of the wall of the casing 5 there is supported an inwardly projecting. L-

shaped contact 20, and at an opposite position and aligned with the contact20 is another similar contact 21. On the same side of the casing as the contact 21 there is another similar contact 22 spaced from the contact 21 at such a distance that when the contacts 20 and21'are engaged by the flange 18, the flange 19 will engage the said contact 22 shown in Figure 2 of the drawings. It will be obvious that the handle 8 serves as a.' means for drawing the shaft 'I outwardly and pushing the same inwardly to the position shown in Figure 2. It will be obvious that the shaft 'I 100 maybe locked in two outward positions through the cooperation of the detent 11 with either notch 12, 13. When the detent 11 is positioned in the notch 13, the spool is out of contact with the contacts 20, 21 and 22, but when the detent 1l is positioned in the notch 12 the ange 19 contacts the contacts 20, 21, in this position being out of engagement with the contact 22. The utility of the structure just described will be evi--l dent as the description proceeds. The casing 6 119 lated from the shaft 7. The formation of the4 casing completely of dielectric material provides a device which meets all of the safety requirements.

My invention being designed tobe used in conjunction with the regular high tension battery ignition system used on most types of internal combustion engines is installed by cutting the primary and secondary wires on the regular high tension coil C and connecting the auxiliary coil unit therewith.

The description of parts and, the operation of my invention is as follows:-

The regular ignition switch S is first turned on, as is ordinarily done in starting the engine. Then, to put into operation my invention the switch button 8 is pushed in to bring the flange, 18 of the spool 17 into contact with the points 20 and 21. The current from the battery B then flows through the wire 23, to point 20, through spool flange 18, to point 21, and through the wire 24, to the connection v25. Part of this current flows through the wire 26 into the winding of the electro-magnet 27 to the ground 28 and causes the electro-magnet 27 to attract the armature 29 carrying the points 30, 31, insulated from each other, which are normally held in contact with the fixed contacts 32, 33 by the coil spring 34, so that the points move into contact with the fixed contacts 35, 36. Consequent upon engagement of the points 30, 31 with the contacts 35, 36 the balance of the current in wire 24 ows from the connection 25 through the wire 37 and into the primary winding 38 of the auxiliary high tension coil 39 and through Wire 38' to the stationary point 40 and the spring mounted vibrator point 41 and to the ground as indicated at 42. This sets up a magnetic ux in the core 43 `of the auxiliary coil 39 causing the vibrator point 41 to vibrate, thereby building up a high frequency,'hgh tension current in the secondary winding 44 of the auxiliary coil 39. This high tension current then ows from the secondary winding 44 through the wire 45 and the engaged points 36, 31 to the center of the distributor cap 46 and is distributed to the proper spark plug of the engine by the rotor in the distributor,causing a high frequency, high tension sparking between the points of the spark plug as long as the breaker points in the distributor are open or in cylinder firing position. A condenser is placed across the breaker points to reduce sparking at the points and induce a stronger spark in the secondary winding 44 of the auxiliary high tension coil 39. v

When the engine has been turned over by the starter motor thereof or by hand cranking sufflciently so that the breaker points in the distributor have closed, current from the battery B vill ow through the point 20 in the hand switch 5 through the flange 18 Vand the body of the spool 17 and through the fiange 19 to the point 22, then through the Wire 47 into the small winding 48 on the core 43 of auxiliary coil 39. The small winding 48 is wound accumulative magnetically to increase core iiux around the core 43 of the auxiliary coil. The opposite end of the small winding 48 has wire 48' leading to point 35 engaged with point 30 and the breaker points which are grounded. This arrangement provides for building up sufficient magnetic force in the core`43 of the auxiliary coil to draw the spring mounted vibrator point 41 awayfrom the stationary vibrator point 40 to hold the point 41 in this non-operative position and disengaged from the point 40 until a piston of the engine has reached the proper firing position in the cylinder and the breaker points in the distributor again open and break this circuit, which will allow the vibrator point 41 to again vibrate and create a. high frequency, high tension spark in the spark plug.

When the engine has started the switch button 8 may be pulled out or released so as to disengage the detent 11 from the small notch 11a. The coil spring 14 will then push the switch rod 7 outwardly until the catch 11 drops into the notch 13 in the rod 7. This will move the fianges 18' and 19 of the spool 17 away from the points 20, 21 and 22 and hold the spool 17 in this neutral position. This cuts the battery current off from the electro-magnet 27 so that it immediately permits the armature 29 to be returned by the spring 34 with its points into contact with the fixed contacts 32, 33, which action disconnects the auxiliary coil 39 from the regular ignition `system and permits the engine to operate on its regular ignition system.

An important benefit derived from my invention is that, in starting the engine, with the switch button 8 in the full inward position, a strong vibrating spark is delivered to the spark plugs continuously from the moment the breaker points in the distributor open until they close again, which will ignite' the charge of gas in the cylinder much more readily than can an ordinary spark, even though the mixture may not be correct, the spark resulting at the plugs being much more intense and of much longer duration than the spark produced by the regular ignition system. It is obvious that in this arrangement it is the circuit breaker which controls the incidence and duration of the spark.

This important feature of my invention is achieved by the provision of the small winding 48 around the core 43 of the auxiliary coil 39, which is energized`each time the breaker points in the distributor close so as to pull the vibrator point 41 away from the stationary vibrator point 40 and hold it in this non-operative position until the distributor breaker points again open. This arrangement provides a well timed spark at the spark plug for starting as current is not permitted to flow to the spark plugs until the piston is in the proper ring position in the cylinder and the distributor breaker points are open, which is the proper time for the l spark to occur.

Another advantage of my invention is that, should the regular ignition system of the engine become disabled due to failure of the distribut'or breaker points to open or to close or to operate in synchronism, burning out of the regular ignition coil or grounding or open circuiting of a condenser, the motor may be kept running merely by pulling the switch button 8 outwardly until the catch 11 drops into the second notch 12 in the rod 7 of the switch 5 in which position the fiange 19 of the spool 17 is in contact with the fixed contacts 20 and 21. 'I'his will let the battery current flow into the wire 24. and energize the electro-magnet 27 so that it pulls the points of the armature 29 into contact with the fixed contacts 35, 36 so that the regular ignition coil C is cut out and the auxiliary ooil is cut into the circuit as explained above. With the switchrod rI in the position -stated, the fixed contact 22 will not be in contactwith the 4spool 17 in the switch 5 so that no current flows through the wire 47 to the small coil 48 and to the distributor breaker points and this part of the system remains inoperative. The point 4l now vibrates uninterruptedly and the auxiliary coil 39 functions continuously, the high frequency, high tension current being distributed to the spark plugsentirely by the rotor in the distributor. While the motor may be run on the auxiliary coil in this mannerindenitely, it should only be done as an emergency measure until the regular ignition system can be repaired.

Another advantage of my invention in starting the engine is the fact that it will operate efliciently even when the voltage and amperage of thebattery current is much below normal due to heavydrain imposed upon it by the starting motor in attempting to start av cold motor or by high resistanceslikely to -occur in the numerous connections in the ordinary ignition system, while the regular Iignition system requires a fully charged battery in order to operate eiciently and develop, a strong spark.-

My invention will function perfectly in starting, even though the breaker points in the distributor are so badly burned or pitted that it would be practically impossible to start the motor with the regular ignition coil C. The reason for this is that the ordinary coil as commonly used requires approximately a six ampere current flow through the breaker points in orderto Work properly, while my auxiliary coil requires only one-half ampere current through the breaker points of the distributor to operate eiiiciently.

g It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred embodiment of the same, and
